In order to identify novel genes related to the carcinogenesis of human hepatocellular carcinoma(HCC),we utilized the eDNA microarray technology to discover differential gene expression profile between HCC tissue and its corresponding non-cancerous liver tissue.We found a cluster of genes with abnormal expression pattern in HCCs.Furthermore,the upregulated expression of 6 genes in HCC samples was confirmed using Northern blot.Among them,we selected Dickkopf-1(DKK1) for further investigation.
